A chip that keeps time (almost) like an atomic clock
For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...
The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...
The Department of Defense has awarded quantum technology firm Infleqtion an $11 million contract to help it speed up the development of its atomic timing technology. Atomic clocks are one of the most ...
This particular clock is technically an ion clock, which is different from the more common atomic clocks that are based on measuring the resonant frequencies of a single cesium atom to regulate time ...
The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...
Where and why tiny, portable, atomic clocks and their precision are needed. How atomic clocks are no longer room- or box-size arrangements. The size, power, and other metrics of a latest-generation ...
The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...
QuantX personnel conducting environmental testing on the optical frequency comb, which is a key optical atomic clock technology that will be launched into space for testing. (QuantX Labs) ...
CHANDLER, Ariz., Jan. 22, 2020 (GLOBE NEWSWIRE) -- As reliance on precise frequency and timing increases due to the Global Navigation Satellite System (GNSS) enabling 5G communication networks, data ...
Atomic clocks have long served as the benchmark for precise timekeeping by utilising the stable frequency of atomic transitions as a reference. Recent developments focus on harnessing coherent ...
